`APPARATUS FOR VMEYLT'ING ANCHOR-ICE.

srEcIrIeMIorI` forming perrorv Letters Patent 4rrafaraeoi, dated Jungle, 1883.

Application ined February-23,1853. (No modem l useful Improvement in Means for Removing Anchor-Ice, of which the following is a descrip tion sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure l is an isometrical perspective view, representing the apparatus in use; Fig, 2, 'a side elevation,representing it detached or not in use; and Fig. 3, a sectional view.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates more especially to means for removingthe anchor-ice which forms or accumulates at or near the screens of water courses or aqueducts and in the flumes or gateways of mills, and it consists, first, in a jet of steam applied under water directly to the ice by means of a pipe, hose, or any other proper appliance for the purpose; secondly, in a ilume, canal, aqueduct, or water-course provided near" its gateway or screen with a steam pipe or pipes arranged in such a manner as to enable steam to be brought into direct contact with the anchor-ice under water; and, thirdly, in an apparatus having a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, by which a more effective device for this purpose is produced than has heretofore been employed.

It is ``well known that a great deal of trouble exists in all cold climates, arising from the formation or accumulation of anchor-ice in iiumes, canals, aqueducts, and other water-courses, more especially at or near the fine screens usually employed for straining the drinking-water supplied to towns and cities by means of aqueducts, the ice frequently choking up the screens to such an extent as to render it difiicult to obtainaproper supply of water. My improvement is designed to obviate this difficulty, and to that end I make use of means which will be readily understood by all conversant with such matters from the following explanation, its eX- treme simplicity rendering an elaborate descriptionunnecessary. k

In the drawings,'A represents theiaqueduct or fiume, and B the screen or strainer. Arranged near the screen, on its upstream side, there is a frame-work, C, as best seeninFig. 2, the frame consistingof the 'side pieces, D E, and crosspieces F GII I, composed of steam-pipes properly coupled together; This frame-work is preferably arranged to slide vertically in the ways d d, ,enabling it to be readily removed in the summer or whenever occasion requires, and is represented in Fig. 1 as partially elevated. A steam-pipe, J, connects the frame with a boiler for supplying steam, and branching from this there is a pipe, K, for use in combination with the hose L, which is provided with the `double nozzle M. At the sides of the pipe J ,where it connects with the piece F, there are two stopcocks,Z a, and there are also stop-cocks f g h, arranged respectively at the ends of the pieces G H I, as shown; but the stop-cocks may all be dispensed with, if desired. The pieces F G H I are perforated on their upstream sides forthe Vemission of steam, this being preferable to having them perforated on' all sides, as it tends to concentrate or direct the steam onto the ice to the' best advantage and with the least waste.

In the use of my improvement the frame O is inserted in the ways d d and pushed down to the bottom of the aqueduct, after which itis properly connected with the induction-pipe J. Steam is then let into the apparatus, and, passing into thepiecesrl G I-I I, will be emitted through the p erforations i and brought into direct contactwith the ice, which will be rapidly melted, the unmelted ice being carried bythe current down against the frame to take the place of that melted until the entirebody is dissolved.

The object ofthe stop-cocks in the frame-work is to control the steam and direct it to any point desired, or to use it in every alternate crosspiece.

The nozzle M is provided withtwo dischargeoriiices, j; but a greater or less number may be employed, if preferred. The nozzle is also provided with a socket, N, and handle T, (a section only being; shown,)the handle being of sufficient length to enable vthe nozzle to be pushed downto the bottom of the aqueduct and manipulated to bring it into contact with all IOO parts of the screen in directing the steam onto the ice.

The hose may be used either with or without the frame-work when properly connected with a boiler or pipe for supplying steam, but is preferably used as auxiliary to the rest of the apparatus.

It will be obvious that the' framework may be permanently applied or arranged to be read ily detached, and may be provided with any number of cross-pieces, if preferred. I do not, however, .wish to be understood as confining myself to the use of live steam, as exhauststeam may be used, if desired, or to the employment of any special number or arrangement of pipes, or to perforating them on one side only, as these features may be varied greatly without departing` from the spirit of my invention.

may be directed into one or more of said pipes,

substantially as described.

3. An aqueduct or flume provided with a screen,withvertical ways in front thereof, and with a frame of steam-pipes vertically adjust able in said ways, substantially as described.

4. In an apparatus for removing anchor-ice from watenways, a steam-nozzle provided with a pipe connected with a flexible steam-supply pipe, and with a socket having an elongated handle, whereby the nozzle may be operated beneath the water, substantially as described.

5. n a device substantially such as described, the framework C, consisting of the perforated pieces F G H l and sides D E, in combination with the pipe J, substantially as set forth.

6. In adevice substantially such as described, the framework C, provided with the stopcocks Z a f f/ 71 substantially as and for the pur pose described.
